You can now link up to three push groups to a campaign at once — for example, a system warm-up sequence plus your own event-based pushes.
- Up to 3 groups per campaign, of which at most one can be a system group.
- Subscribers receive pushes from all linked groups.
- The campaign form has a multi-select instead of a single choice.
- Groups can be bulk-assigned to multiple campaigns; the campaigns table has a column and a filter by groups.
Where to find it: Campaigns → edit → Push Groups.
